Background: It is common to have adult patients with unilateral severely depressed nasal dome after the initial unilateral cleft lip repairs were carried out in infancy. The main surgical treatment includes repositioning the cleft alar cartilage to a more normal anatomical position. In this study we present our results using Potter and Dibbell techniques. Aim of the study: This is a retrospective study showing two different techniques used forsecondary correction of severely depressed alar dome in unilateral cleft lip adult patients. Patients and Methods: Eleven adult patients (7 male and 4 female) ranging in age from 20 to 27years (average 23 years) presented between Feb.2009 and Jan.2012 for secondary correction of unilateral cleft lip nasal deformity. The initial cleft lip repairs were done by other surgeons somewhere else, without primary nasal correction or any sort of preoperative molding device.Thepatients were divided into two groups according to the surgicaltechnique used: group AreceivedDibbelltechnique (7 patients) and group B received Pottertechnique (4 patients). Tajima inverted-U incision was used for all cases. Results: The results were evaluated on the basis of the degree of symmetry between the cleft and noncleft nostrils. The length of the longitudinal axis of the nostril and the width at the midcolumella level were taken at the time of final follow-up, which was between 6 months and 2years. An excellent result was defined as a deviation of 10 percent or less with the noncleft nostril. A good result was a deviation between 11 and 20 percent with the noncleft nostril, a fair result was a deviation between 21 and 30 percent with the noncleft nostril, and a poor result was a deviation greater than 30 percent with the noncleft nostril. Excellent results were achieved in 7 patients with minimal alar-columella web deformity and a satisfactory symmetry of the nostrils. Three patients showed good results. One patient showed fair result. Conclusion: Modifying Dibbell bipedicle flap through displacing it inferiorly to involve lip tissue to replace a deficient nostril floor, found to be applicable for achieving a reasonable secondary correction of severely depressed alar dome in unilateral cleft lip adult patient.
